Giveaway Wheel — A Fair Winner Picker for Streamers, Creators, and Events
Run a giveaway your audience can actually trust. Drop in every entry, hit spin, and let cryptographic randomness pull the winner live. Works offline, no signup, nothing to install.
Twitch drops, Instagram comment contests, classroom raffles — one wheel, one provably fair winner
Mengapa Memilih wheel.expert?
Pick a Winner Nobody Can Question
Paste every entry, spin, and the result is settled by the algorithm in front of everyone watching. No 'my cousin won again,' no quiet thumb on the scale — just one name the whole chat saw land.
Built to Be Screen-Recorded
Run the giveaway wheel on stream or hit record before you spin. The slow wind-down and the final stop are all on camera, so your proof of fairness is the clip itself — share it and the argument's over.
Draw Several Winners Without Repeats
Giving away five codes, not one? Spin, remove the winner, spin again. Each name drops out of the next round automatically, so you get five distinct people instead of the same lucky handle twice.
Genuinely Equal Odds for Every Entry
The draw pulls from the Web Crypto API — crypto.getRandomValues(), the same randomness browsers use to generate security keys. A handle entered first has identical odds to the last one pasted in. There's no hidden weighting unless you add it on purpose.
Paste a Whole Comment List at Once
Export the entrants from your giveaway, paste the block in, and the wheel splits it into entries for you. No retyping two hundred usernames by hand thirty seconds before going live.
Free, No Account, Nothing Stored
You're not signing up, you're not buying credits, and the entries aren't kept after you close the tab. Open it, run the draw, done.
How to Run a Giveaway With the Wheel
Load Every Entry
Paste your list of usernames, names, or ticket numbers. Pull it straight from comments, a sign-up sheet, or a Twitch chat export — one entrant per line and the wheel does the rest.
Start Recording
Going live? You're already covered. Drawing off-camera? Hit screen-record first. A thirty-second clip of the spin is the cleanest proof a giveaway was fair, so capture it before the wheel turns.
Spin in Front of Everyone
Tap the center and let it run. The wheel slows, settles, and stops on one entry — decided the instant you spun, not by where it looks like it landed.
Announce, or Draw the Next Winner
Got your winner? Call it out. Need a second or third? Remove the name and spin again — past picks sit in the history panel so you can read the full winners list back at the end.
How Creators and Organizers Actually Use It
Live Stream Giveaways
Twitch and YouTube creators run the wheel on screen so the draw happens where the audience can see it. The spin becomes part of the show, and 'it was rigged' never gets traction because everyone watched it stop.
Instagram and TikTok Comment Contests
Copy the commenters into the wheel, record the spin on your phone, and post the clip as your winner announcement. Followers see the actual draw instead of a name you could have just picked.
Event and Conference Raffles
Project the wheel on the big screen, load the ticket numbers, and draw the door prizes in front of the room. No paper hat, no reaching around for the 'right' stub.
Classroom and Club Prize Draws
Reward a reading challenge or a fundraiser with a transparent draw. Every student watches the same spin, so the kid who didn't win still saw it was square — which heads off a lot of 'that's not fair.'
Small-Business and Brand Promos
Running a launch-week giveaway across your channels? Pool the entries from every platform into one wheel and draw once, on video. One clip covers the whole promo and doubles as your fairness receipt.

Seleksi yang Benar-Benar Acak - Cara Kerja Algoritma Kami
Berbeda dengan banyak spinner yang menggunakan Math.random(), wheel.expert menggunakan Web Crypto API (crypto.getRandomValues()) untuk menghasilkan angka acak yang aman secara kriptografis. Ini adalah API yang sama yang digunakan oleh aplikasi penting seperti pembuat kata sandi.
API Kripto Web (CSPRNG)
Kami menggunakan crypto.getRandomValues(), sebuah Penghasil Angka Acak Pseudo-Acak (CSPRNG) yang Aman Secara Kriptografis yang terpasang di semua browser modern. Hal ini memberikan keacakan berkualitas tinggi dari kumpulan entropi browser, jauh lebih baik daripada Math.random() yang dapat diprediksi.
Algoritma Seleksi yang Tidak Memihak
Ketika semua entri memiliki bobot yang sama, kami menggunakan pengambilan sampel penolakan untuk menghilangkan bias modul - masalah umum dalam pemilihan acak. Hal ini memastikan bahwa setiap entri memiliki peluang yang sama secara matematis untuk dipilih. Dengan entri berbobot, probabilitasnya sebanding dengan bobot yang diberikan.
Transparansi Sisi Klien
Semua pemilihan acak terjadi di browser Anda pada saat putaran. Kode ini terbuka dan dapat diperiksa melalui DevTools browser. Untuk hadiah dalam jumlah besar, kami merekomendasikan rekaman layar selama putaran sebagai bukti keadilan bagi penonton Anda.
🔍 Verifikasi sendiri: Buka DevTools (F12) dan periksa pembuatan nomor acak kami di Konsol. Kami menggunakan window.crypto.getRandomValues() - API kriptografi yang sama yang digunakan oleh bank dan aplikasi keamanan.
